ABSTRACT – The effect of environmental temperature on performance and carcass characteristics in broilers pair-fed and two levels of metabolizable energy was evaluated. One hundred and sixty Hubbard male broilers, with 21 days of age and 791±4.12 g average initial weight were allotted either under thermoneutral environment (23.3±0.58ºC) or under hot environment (32.3±0.31ºC) up to 42 days of age. A completely randomized design in a 2 x 2 factorial arrangement (level of metabolizable energy [3075 and 3300 kcal of ME/kg] […]
